Hm, but this way free_on_busy, even though constant, cannot be optimized away? Can't you just move the dev_xmit_complete() check out into dev_direct_xmit() instead? That way you can just drop the bool, and the below dev_direct_xmit()should probably just become an __always_line function in netdevice.h so you avoid the double call.
Good suggestion! I'll spin a v2. Björn
